the plunger by means of bolts 29 and is provided with depending spaced-apart portions 30 for receiving the marking die 31 therebetween, the latter being freely rotatable on a pin orshaft 32 retained in the portions 30, asby cover plates 33. As indicated,

the marking die 31 is in the form of a roller having the desired characters upon the periphery thereof, and is adapted to be rotated m by-the passage of the tubing a in contact therewith.

For adjusting the arm 14 and its marking die 31 to the proper position with respect to 1 the tubing a, I have providedlinks 34 eXtend-' ing through slotted openings 34a in the base member 6. These links are pivoted to arm said opening forguiding the arm 14 by con-. with, the sides of the U-shaped mem tacting bar is. 1

'In operation, assuming the marking device and its mounting are positioned on a-roll housing in the manner described, for example,on thehousing for the finishing rolls of a tube mill,'arm '14 is lowered by means of.

the screw 39land the links 34 until the die roller 31 is in a position just beyond its line.

of contact with the outer surface of the tubing 6 a." .The adjustable stop 40 is lowered until it is spaced from the arm 14 but a slight amount, thus' providing for slight play'in the arm 14.

. Theltubi'ng passes through the various rolls and through the finishing rolls while still in 5=a heated condition. the tubing a engages and rotates the roller 31, the arm 14 and its parts will be moved slightly toward the stop 40. The remainder of the distance neces- A sarily travelled by the roller 31 to engage the 0"-"outer' surface of the tubing produces a sliding movement of the plunger 20 againstthe action of the spring 22, thereby urging said.

roller firmly against the tubing to produce a good impression thereon. :11 'Since the characters are on the periphery of the roller, the marking will take place continuously during the passage of the tubing thereunder. I I V g It is to be noted that any inaccuracies in the no diameter of the tubing will be compensated for by means] or the adj ustable mounting and spring action just described, and thatfmy in-. vention is capable of use for marking varie ous sizes of tubing or the like."

63 For the purpose of cooling'the die roller 31, an opening 44is provided through the plunger 20 and the die holder 28 for supplying the stream of cooling fluid to the roller through a flexible conduit 45.

Fi .2 illustrates the vertical housing A of the German-type tube mill, having rolls 4a rotatable therein. In this instance, the marking device may be mounted in parallel.- ism with the tubing a by' means of an angle member 46 secured to the housing. The base member 6 is in such case bolted or otherwise secured'to the horizontal flange of said angle by bolts 47."

' Itwill be understood that my invention is not to be limited to the particular form or application shown herein, but may be applied to the marking of other products and in combination with other devices.

Various changes and modifications are contemplated, provided they fall within the scope of the following claims.

I claim:

1. A marking device adapted formarking I a moving object including a base member, 7

an arm pivoted to the base member, a resil-.

iently mounted plunger slidable in the "arm, a

die member carried y the plunger, and adjustable'means associated with the arm for positioning the die member in the path of the moving object. 5 j

2. A marking device including a base member, an arm pivoted to the" base mem her, a recess in the arm, a plunger slidable in the recess, a spring retainer secured to the arm and spaced from the plunger, a spring extending between the :retainer and the plunger, and a die member carried by the plunger. i

3. A marking device including a base member, an arm. ivoted to-the basemember, guide, members or the arm,means for adjustablypositioning the arm from the base member, and a die member resiliently mounted in the .arm. V

.4. A, marking device including a base member, an arm pivotedto the base member,

a slidahleeross-head on the base member and a screw therefor, links connecting .the

cross-head and the arm, an adjustable stop member for engaging the arm, and a die member resiliently mounted in the arm.

5. A marking device including a base member, an arm pivoted'to the base member, a cross member on the arm,a U-shaped member secured to the cross member, a resilient-' ly mounted plunger-slidable within the U- shaped member, a die holder secured to the plunger, and a roller die rotatable in the die holderi" 6. marking device adapted for marking a moving object including a basemember, an armpivoted thereto, a recess in the arm, a plunger slidable-in the recess, a spring retainer secured to the arm and spacedfrom;

the plunger, 9. spring extending between the retainer and the plunger, a roller die carried by the plunger, adjustable means associated with the arm for positioning the die in the path of the moving object.

7. In a device for marking tubing and the like, the combination with a roll housing having spaced-apart end members, of a base member secured to and extending between said end members, an arm pivoted to the base member, a resiliently mounted plunger slidable inthe arm, a die member carried by the plunger and adjustable means for positioning the arm Within the housing. s

In testimony whereof I afiix my signature.
